This application is a division :of my Patent .No. 2,102,616, issued December .21, .1937, which discloses :a stove having a rotatable stove body mounted upon a relatively fixed base.

The present invention provides novel and efficient connections between the stationary base and the rotatable stove body, so as to permit rotation of said body and also to allow of raising and lowering thereof, so that the stove body may be arranged at the most convenient elevation for use.

Other features of the invention will hereinafter be more fully pointed out in the annexed detailed description shown in the accompanying drawing and set forth in the appended claims.

The accompanying drawing illustrates one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not as defining the limits 20 of the invention.

Figure 1 is a side elevation of a stove embodying the present invention, with the lower portion thereof partly in central section and partly in elevation.

Referring to the drawing, l designates a suitable hollow standard, shown as comprising a relatively broad base'2 having an upstanding cylindrical portion 3. The upper end of the cylinder 3 is open, and projecting thereinto is a hollow 30 plunger 4, mounted within the cylinder 3 for rotation and vertical adjustment. This vertical adlustment may be accomplished in different ways and by means of various types of mechanism, but, the plunger 4 is shown as threaded at 5 and. cooperating with these threads is an adjusting hand wheel 6 having a threaded hub I screwed on to the plunger 4. In the under side of the hub l is formed a ball race and in the upper end of the cylinder wall is formed a complementary ball race and anti-friction bearings 8 are housed within these complementary ball races, so as to permit rotation of the hand wheel 6 for the purpose of raising and lowering the plunger with respect to the standard when said plunger is held against rotation. The plunger and hand wheel may also rotate together while the base remains stationary. It will be noted, however, that the friction between the hub and the cylinder 3, because of the anti-friction means interposed between the latter two parts, is less than the friction between the hub and the plunger 4, and consequently rotation of the plunger may be accomplished without tending to change the vertical adjustment thereof, although, when the plunger is held against rotation, rotation of the hand wheel will effect such vertical adjustment without the application of undue power thereto.

The upper end of the plunger is flanged at 9 and this flange is secured in any suitable way to the under side of the stove body, indicated generally by the reference character It]. The details of construction of the stove body may, of course, be varied wtihin wide limits depending upon the type of fuel used and also upon the views of different stove designers and the present invention is to be understood as not limited to these details other than as hereinafter specifically pointed out as important to this invention.

Gas is fed to the stove body through a pipe 32 rigid with the stove body and extending downwardly within and coaxially with the plunger 4 and connected to a fuel supply pipe 33 by any suitable connection which will preclude the leakage of gas but which will permit of rotation of the stove body and raising and lowering of the latter. An ordinary hose connection of flexible character will serve this purpose, but, for the purpose of illustration, the pipe 33 is shown as extending into the pipe 32 with an associated packing gland or stuffing box 34 to preclude leakage. This arrangement permits of rotation and change of elevation in the stove body without interfering with the supply of fuel. The same general arrangement may be used to supply oil, if the stove is an oil burner. and it will of course be understood that, in an electric stove, suitable wiring connections and heating elements will take the place of gas connections and burners.

The foregoing detailed description sets forth the invention in its preferred practical embodiment, but it is to be understood that the invention is not restricted to details of construction which may be modified within the scope of the appended claims.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

1. A stove comprising a stove body provided with a centrally located depending portion permanently attached to the stove body, a subjacent base having an upstanding portion, one of said portions being threaded and the other unthread- .ed, and both telescoping with respect to one another to mount the stove body for rotation about the common axis of the telescoping portions, an adjusting member screwed onto the threaded portion and bearing on the unthreaded portion to permit vertical adjustment of the stove body with respect to the base through rotation of the adjusting member while the threaded portion remains stationary, and antifriction means interposed between the adjusting member and the unthreaded portion to insure less friction between the adjusting member and the unthreaded portion than between the adjusting member and the threaded portion, whereby the stove body may be freely rotated without varying its vertical adjustment.

2. A stove comprising a stove body provided with a centrally located depending threaded plunger permanently attached to the stove body, a subjacent base having an upstanding coaxial unthreaded cylinder into which said plunger telescopes to mount the stove body for rotation about the common axis of the plunger and cylinder, an adjusting member screwed onto the threaded plunger and bearing on the unthreaded cylinder to permit vertical adjustment of the stove body with respect to the base through rotation of the adjusting member while the threaded plunger remains stationary, and antifriction means interposed between the adjusting member and the unthreaded cylinder to insure less friction between the adjusting member and the cylinder than between the adjusting member and the plunger, whereby the stove body may be freely rotated without varying its vertical adjustment.

3. A stove comprising a stove body provided with a centrally located depending threaded plunger permanently attached to the stove body, a subjacent base having an upstanding coaxial unthreaded cylinder into which said plunger telescopes to mount the stove body for rotation about the common axis of the plunger and cylinder, a hand wheel screwed onto the threaded plunger and bearing on the unthreaded cylinder to permit vertical adjustment of the stove body with respect to the base through rotation of the hand wheel while the threaded plunger remains stationary, and antifriction means interposed between the hand wheel and the unthreaded cylinder to insure less friction between the hand wheel and the cylinder than between the hand wheel and the plunger, whereby the stove body may be freely rotated without varying its vertical adjustment.
